tankless water heater leaking (Takagi Jr.)
I've been a happy tankless user for a few years, but just last week my Takagi Jr sprang a leak (drips less than one drop per second.) I took a picture of the inside part that is leaking and it looks like it might just be some gaskets. But they have some press-on clip fittings that I've never worked with, so I don't know if it is a user-serviceable part.
I'm a little disappointed in the leak. The unit has been in service since January 2007. Would water hammer strain those gaskets?
Not sure if this is a clue, but the hot water circ pump runs 24/7. (Theorizing about installing a motion-sensor switch.)
